PLEASURE BUOY FOR SEASIDE' RESORTS Filed July 11, 1929 i zwezz W fczeic Patented Dec. 3%, 1930 STATES MAX WILI-IELM IDEN, OF ALTONA, GERMANY PLEASURE BUOY FOR SEASIDE RESORTS Application filed July 11,

The present invention concerns a pleasure buoy which is particularly suitable for seaside resorts. It consists of a floating body surmounted by a platform. The former is pivotable around a vertical pole and is arranged in such a manner that it can be made to rise and fall. The idea is that the players, by jumping uniformly on to the buoy, cause the latter to be submerged into the water, is after which the buoyancy of the water tends to push it upward again. But frequently and rhythmically jumping on to the buoy, the players cause the latter to dip more and more into the water, but each time it is again pushed upward more and more. The buoy may be made of any size desired, from the smallest to the largest (after the manner of a roundabout), and may be made to accommodate fifty persons or more. The pole may 29 be firmly secured to the bottom of the waterspace or it may be connected to floating pontoons by means of props. The players may hold on to the buoy by gripping a tube fitted to it, which could be provided, if desired, with handles or other fittings, such as ropes such as are used for giants strides, etc.

The drawing illustrates three different ways of constructing the buoy, viz.:

Figure 1 is a View in section, partly in elevation, of one form of the improved pleasure buoy.

Figure 2 is a side elevation showing another form.

Figure 3 is a broken side elevation showing a slightly modified form of buoy proper.

The principal parts of the device are the buoy body (a), the guide tube (6) and the pole (0). The buoy body may be used for advertising purposes, whilst the guide tube may also be made into the shape of some article which it is intended to advertise, e. g.. a tooth-paste tube, etc.

The buoy (a) illustrated in Figure 1 possesses a tapering lower portion surmounted by the platform (a1). If some players stand on the platform (a1) and if they uniformly jump on to the buoy, the latter will be dipped more and more into the water into the position (a2), but if the jumping exercise is continued, it will rise and fall alternately be- 1929.

tween that position and the high position shown at ((18). The type illustrated in Figure 2 differs from that illustrated in Figures 1 and 3 in that the pole is not secured to the bottom of the water, but is fastened to a iiinumber of props ((Z) attached to the floating bodies (6). For the rest, the mode of using the buoy is the same, and so is its general shape, except thatinstead of tapering downward-its lower portion is rounded.

Figure 3 illustrates a large buoy provided with a large platform capable of accommodating several persons. High above the buoy in the direction towards the tube (6) there is a conical casing to which a number of handles (g) are fitted. Thus, the persons on the buoy are obliged to take up their posi tions near the edge of the buoy, which ensures the uniform distribution of the load. The type illustrated in Figure 2 may also be used on land, provided that in place of the floating bodies a scaflolding is used. The handles for causing the buoy to move will be designed difi erently according as the latter is to be used as a jumping buoy or a rotating buoy.

The buoy may also be designed after the manner of a table, and meals may be served on itwhilst it is in the water. Owing to the guide of the pole (0) there is no possibility I of the table tilting over.

l/Vhat I claim to be new is:

1. A pleasure buoy including a guide rod, means for supporting the guide rod in sub stantially vertical position in a body of water, and a buoy proper slidable on the rod and normally sustained in a predetermined position with respect to the surface of the water by its buoyancy, said buoy proper being freely slidable longitudinally of the rod.

2. A pleasure buoy including a guide rod, means whereby the rod may be held in vertical position in a body of water, a hollow body encircling the rod, and a tube carried by the body and slidably embracing the rod beyond the body, the buoyancy of the body serving to maintain it at the surface of the water to permit it to move longitudinally of thg rod through the guiding influence of the tu e.

3. A pleasure buoy including a guide, means whereby the guide may be held in vertical position in a body of Water, and a buoyant body freely slidable on the rod and capable of being moved in use to a position below its normal position on the surface of the Water or to a position above such normal position.

4. A pleasure buoy including a guide, means for supporting the guide in substantially vertical position in the body of water, and a buoyant body mounted on the guide and capable of free vertical and free rotary movement- With respect to said guide 5. A pleasure buoy including a guide,

means for supporting the guide in substantially vertical position in the body of Water, and a buoyant body mounted on the guide and capable of free vertical and free rotary movement with respect to said guide, said body being of hollow form with its upper surface arranged as a platform.

In testimony whereof I aflix my signature.
